Birds are masters at hiding illness—a survival instinct that makes early disease detection challenging. Understanding common health problems and recognizing subtle signs of illness can save your bird's life. This guide covers prevalent avian health issues and preventive care strategies.
Respiratory Infections
Respiratory problems are among the most common health issues affecting pet birds.
Symptoms
Difficulty breathing, tail bobbing with breaths, nasal discharge, sneezing, voice changes, and reduced activity. Birds may sit fluffed up at the cage bottom.
Causes
Bacterial, viral, or fungal infections, often triggered by poor ventilation, dusty environments, temperature fluctuations, or stress. Aspergillosis (fungal) is particularly dangerous.
Prevention
Maintain proper cage hygiene, ensure good ventilation, avoid drafts and temperature extremes, minimize stress, and quarantine new birds before introducing them to existing birds.
Treatment
Requires immediate veterinary care. Treatment may include antibiotics, antifungals, or supportive care with oxygen therapy and warmth.
Nutritional Deficiencies
Improper diet is a leading cause of health problems in pet birds.
Vitamin A Deficiency
Common in birds on seed-only diets. Symptoms include respiratory problems, eye discharge, poor feather quality, and weakened immune system. Prevented by feeding dark leafy greens, carrots, and sweet potatoes.
Calcium Deficiency
Causes brittle bones, egg binding in females, and seizures. Provide cuttlebone, mineral blocks, and calcium-rich vegetables. Breeding females need extra calcium supplementation.
Iodine Deficiency
Particularly affects budgerigars, causing thyroid enlargement (goiter). Symptoms include difficulty breathing and regurgitation. Prevented with iodine supplementation or cuttlebone.
Obesity
Results from seed-only diets and lack of exercise. Leads to fatty liver disease and shortened lifespan. Control portions, switch to pellets, increase vegetables, and ensure daily exercise.
Psittacosis (Parrot Fever)
A serious bacterial disease that can affect humans.
What It Is
Caused by Chlamydia psittaci bacteria, psittacosis affects many bird species and is zoonotic (transmissible to humans).
Symptoms in Birds
Lethargy, loss of appetite, ruffled feathers, nasal discharge, difficulty breathing, and bright green droppings. Some birds show no symptoms but shed bacteria.
Human Risk
Humans can contract psittacosis through inhalation of contaminated dust. Symptoms resemble flu. Seek medical attention if you develop respiratory symptoms after bird exposure.
Prevention and Treatment
Buy birds from reputable sources, quarantine new birds, maintain cleanliness, and ensure good ventilation. Treated with specific antibiotics under veterinary supervision.
Behavioral and Feather Problems
Psychological issues often manifest as physical problems.
Feather Plucking
Birds pull out their own feathers due to stress, boredom, medical issues, or poor diet. Requires thorough veterinary exam to rule out medical causes, then address environmental and social needs. Provide enrichment, social interaction, and foraging opportunities.
Screaming
Excessive vocalization may indicate boredom, attention-seeking, or health problems. Establish routines, ensure adequate sleep, provide enrichment, and don't reinforce screaming with attention.
Aggression
Can stem from fear, hormonal changes, or territoriality. Never punish aggressive birds. Identify triggers, respect boundaries during breeding season, and consult an avian behaviorist if needed.
Egg Binding
A life-threatening condition affecting female birds.
What It Is
Egg binding occurs when a female cannot expel an egg from her reproductive tract. It's a medical emergency.
Symptoms
Straining, sitting on cage floor, fluffed feathers, labored breathing, swollen abdomen, and lethargy. May see egg stuck in vent.
Risk Factors
Calcium deficiency, obesity, first-time layers, small or malformed eggs, and young or old birds.
Prevention
Ensure proper calcium and vitamin D3, maintain healthy weight, discourage breeding behavior by reducing daylight hours and removing nesting materials. Seek immediate veterinary care if egg binding is suspected.
Parasites
Both internal and external parasites can affect pet birds.
External Parasites
Mites and lice cause itching, feather damage, and skin irritation. Red mites are blood-suckers active at night. Treat with avian-safe products and thoroughly clean and disinfect the cage.
Internal Parasites
Intestinal worms and protozoa like Giardia cause weight loss, poor feather condition, and digestive issues. Diagnosed through fecal testing and treated with specific antiparasitics.
Prevention
Quarantine new birds, maintain strict hygiene, prevent contact with wild birds, and schedule annual fecal exams.
Conclusion
Prevention is the cornerstone of avian health. Proper nutrition, clean environment, stress reduction, and regular veterinary check-ups prevent most common bird health problems. Learn what's normal for your bird—their typical behavior, droppings, and appearance—so you can quickly identify changes. Birds decline rapidly when ill, making early intervention critical. Never hesitate to contact your avian veterinarian if something seems wrong. Quick action can mean the difference between life and death for your feathered companion.
